Latos (3-3), who hails from nearby Coconut Creek, beat the Marlins for the first time in eight career starts. He allowed one run on five hits and four walks while striking out five.

Aroldis Chapman got the last three gouts for his 25th save in 27 chances.

Marlins All-Star slugger Giancarlo Stanton homered in his third consecutive game to give him a National League-best 26. Jarred Cosart (0-1) gave up four runs and four hits in 5 1-3 innings in his Marlins debut one day after being acquired from Houston.

Miami has lost three straight after winning six in a row.

The Reds' Todd Frazier and the Marlins' Jordany Valdespin traded RBI singles before the Reds scored three runs in the sixth inning to take a 4-1 lead.

Cosart retired the first nine batters he faced and recorded his first hit in the majors before running into trouble in the pivotal sixth. Cosart was pulled after he loaded the bases in favor of Chris Hatcher, who immediately allowed a two-run double to Ludwick.

Stanton's solo homer in the eighth pulled Miami to 4-2.

TRAINER'S ROOM

Reds: Brandon Phillips (left thumb) joined the team on the road trip and fielded ground balls on Thursday, but there is no timetable of when he will be able to swing the bat.

"I don't think he's close, but I don't know what close is whether it's five days or two weeks, I'm not sure," said Reds manager Bryan Price, who added that the target date for Phillips' return remains late August.

Marlins: All-Star pitcher Henderson Alvarez was placed on the 15-day disabled list before the game with shoulder inflammation. Alvarez, who was scheduled to start Sunday's game, is 8-5 with a 2.48 ERA.

"I don't know if it's in the same spot or the same type of pain he had last year, but we're going to get him checked out and make sure we get him healthy," Marlins manager Mike Redmond said. "Hopefully we caught it early enough where it's not a huge deal; just 15 days on the DL hopefully, that's the hope."
